A podcast can be private or public. To access a private podcast, users must enter a username ("spark") and a password (determined below).
Note: Do not use your LDAP (Tufts email) password as your podcast password.

When users add points to this geo-collection they can automatically be prompted
for the values of additional variables. For example, if your map contains information
on individual trees you should probably add variables for tree type, size, condition
and general notes.
For a map about resturants you might add variables for the name, a rating, your favorite dish and the hours
of operations.
